And Figure 9 is a detail of a part utilized in the machine.

In the specific structure employed in the construction illustrated in the drawings the mechanism is supported. by means of the frames or supportsltlflO' which are con nected together by means of the plate 11 to which the standards or supports 12, and 13 are secured. These supports carry the dies which press the commodity into shape and also provide supportssfor certain of the die actuating mechanism and in addition support a conveyorv mechanism provided for feeding the material to the machine. A drive shaft laisemployed which is supported in journal boxes,1.515 which are mounted or carried: by the frames 1()1(). This shaft may be driven in any suitable manner and hasits opposite ends provided wvith crank arms 16 and 17 whicl'rhave e1;

tensions which are arranged in boxes and slide 111 a slot'18 provided in each of the arms 19, the latter being connected to the mechanism 20 and 21 arranged at the opthey can be arranged to assist in forming posite ends of the machine. This mecha nism 20 and 21 is provided for actuating the dies whereby the commodity is pressedv into form, and, as the mechanism at one end of the machine is ident cal with that arrangement at the other an explanation of the structure and operation of one will sufficefor an understanding of both.

' Thesearms 1919 are pivoted upon a rod 22 supported in journal boxes 2323 arranged in the vertical slots 24;v provided in the supports 12 and 13. This rod and its associated mechanism is resiliently held in its lowermost position by means of the transversely arranged rods 25-.25 whic-hare secured at one end to the rod 22 and pass through the plate 11, and are each-provided with a nut 26 and a spring 27 which reacts between the plate and the nut and acts to hold the rod in its lowermost position in the vided with a transversely arranged portion 28, and the respective ends of this last named portion has a cam arm 29 and 30 pivotally secured thereto. These cam arms -which dies are removably attached. In the structure illustrated there are two sets of these bars, one set being operated by one set of cam arms and the other by the other and as these cam arms areoperated alternately one set of bars will be actuated to act upon the commodity while the other is ejecting the finished product and being positioned to receive another roll or bar of the confection. The bars above referred to of one set are designated by the numerals 31 and 32, similar bars of another set are defined bv the numerals 33 and 3a. The bars 31 and 33 are secured to the uppermost- ,cnds of the cam arms and operated along .guideways, 35-35. and 34 are arranged 1n horizontal slots such 2-39 arranged directly below the bars 31 and 33, these last mentioned bars have only a =1O0lil11g motion imparted to them so that the confection and to eject it after it has been formed. To accomplish this, this bar is pivoted. in the supports 12 and 13, at 3C and these supports are provided with limiting pins which prevent the movement of this bar in one direction but allow the same to be moved in the opposite direction when engaged by the pawl ll. These bars are restored to their normal or operative position.

by means of the coil spring 39. This pawl is pivoted to the bars such as and 34-. and is provided to engage the projections such as si provided upon the upper face of the bars such as 38 and 39 to tilt the bars such. as 38 and39 when the former, are moved outwardly. Another bar 42 is utilized which also has a horizontal reciprocable motion so that it may be moved with relation to the feeding mechanism to permit the roll or bar of confection to be alternately arranged upon opposite sides thereof. This bar is arranged in substantially horizontal alignment withthe' horizontally reciprocable bars 32 and This bar d2 acts as a rest for the material while it is being fed to the ma-' chine by the conveyor and also has a die secured to it which cooperates with the dies provided upon the other bars, to press or form the material into the desired shape. This bar is of a width sufficient to allow the material to be placed upon one side of the center thereof while this bar is cooperating with one set of bars or dies so that when this bar is moved to allow the finished product to be ejected from between this last mentioned set of bars,.the bar or roll of confection, previously arranged upon the bar 42, may be arranged between the other set of bars, so that these may at upon the roll or bar to form it into the desired shape. hen the bar 42 is in this last named posi; tion another bar or roll oi confection will be arranged upon the opposite side of the center thereof. This action is continued throughout the whole time that the machine is in operation. This bar 42 is arranged in the horizontal slot 413 and is actuated by virtue of a connection with the swinging arms 1919. This connection in the present structure includes the link it one end of which is connected to the transverse portion of the arm 1 and illilS its opposite end pivotally connected with a sliding block 2-5 arranged in a vertical guideway provided in the supports 12 and 13. This block is )rovided with a cam slot ii, and through the medium of the pin 48 which is arranged in this slot and connected to the reciprocable bar s9 causes the reciprocation of thehar The bar s9 is arranged in a horizontal groove 50 and has one end connected to the bar The dies may be connected to the bars such as in any suitable manner. This horizontally reciprocable bar 42 has the longitudinally extending gable shaped rib 51 secured to it with which is cooperatively arranged an arrangement for releasably holding the bar or roll of confection with relation to this rib. This holding mechanism is provided to hold the confection with relation to the rib during a portion of its travel towards one or the other of the sets of forming dies or bars and is actuated to release the confection to allow it to enter between said dies. This last mentioned mechanism includes the arms 52 and 53 which are pivoted at. 54:, and respectively carry the movable gates 5i and 55, at their opposite ends. These arms are also provided with the transversely arranged extensions '56, which are provided with antifriction rollers which ride upon the cam track 57 one of which is arranged at each end of the machine and is so designed that it will alternately raise and lower said gates to retain and release the roll or bar of confection from the rib 51.

It conveyor generally designated (38 is utilized for conveying the bar or roll of confaction from the spinner to the machine. This conveyor is pivoted at 59 to one of the supports such as 13 and is provided with a lock for releasably locking this portion to the remainder of the device. This conveyor extends from one end of the ma chine to the other and is arranged directly in the center thereof between both sets of bars which carry the forming dies, and includes an endless link chain 61 which is driven by the sprocket wheel 62 and travels over idlers 63 and G l. This chain has socured to it a plurality of grippers 65, 66

and 67, which are operated to close upon the bar and be held in this condition and to also release the bar when they reach various po sitions in the track (38. In addition to grasping and conveying the material through the machine, this mechanism also cuts or scvers the part to he acted upon by the machine from the part ejected by the spinner and in addition also grips this last mentioned part so that it may be subsequently drawn through or arranged in the machine by the conveyor. The track 68 is provided with the flared end (it) and the substantially parallel side walls 70 which tern'iinate adjacent one end of the machine. The flared portion is provided to engage the cutters and grippers and close them and the opposite end is provided to allow the cutters and grippers to open and release the bar or roll of confection. These grippers and cutters are pivotally connected to the chain, and include apair of elements 71, which are pivotally secured to the outer side of the conveyor chain, by means of the lugs or brackets 72. These ele ments 71 are each provided with the inwardl y projecting portions T2 which are arranged so that they will pass below the chain, and are proy'ided to cut or sever the bar or roll of confection. To facilitate this cutting action these inwardly projecting portions are provided with cutting edges so that the roll or bar of confection will be severed when these portions are brought together by the cam track'tlf). An expansion spring 73 is utilized for separating these hinged members after they have passed beyond the influence of the cam track. These hinged ele ments are further provided with gripper lingers T lwhich grip the main portion of the bar of confection sin'iultan-cously with the cutting action, and therefore one piece is severed and the next or succeeding portion is grasped so that it may be drawn through the machine.

These grippers and cutters are arranged in such relation upon the chain, so that one gripper will be releasing the confection approximately at the same time that the cutter of the succeeding one is r-ievcring th s portion from the main bar or roll and grippingthc end of this main portion, so -that the bar or roll nuiy again be drawn through the machine.

The operation of the machine is substantially as follows: The conveyor chain is caused to travel around the wheels (33 and {ii and grip. convey, cut and grip again and release the bar of confection. As the bar of confection is drawn through the machine, the horizontally movalde bar i2 is positioned so that the confection will be arranged at one side or the other of the rib 51 secured to and arranged to extend lengthwise and centrally of the bar Thus as this bar is moved from one side to the other,

illtl lit) a portion of the bar or roll of confection will be alternately arranged HPOHOPPOSHG sides of this'rib,'as-it1is fed to the machine by the conveyor. Thisrib may have the inclined sides as shown so thatthe confection will roll against the gates and to the forming dies when-released by the conveyor and the'rgates, thus as the confection is alternatelyarrai'iged upon opposite sides of the rib, the'forming dies "Will alternately have the confection fed thereto. The bars which have the dies secured thereto are then actuated to press the material intothe desired shape, after which the confection =will be ejected outwardly away from thecenter of the maeliine'first fromone side and then the other. As before sta'tedprovision is niadenhereby either set of formil'ig dies or bars which carry these mayyieldin the event that-a bar of relatively large dimension should be fed to theother.

To compensate for this contingency the shaft is yield-ably held in the slot 2% by means of the rods itiand the spring 27, this a rrangement' allows theshaft and its asso- 1 ciated parts to move'without resulting in any injury thereto. To drive the co veyor Cllilill,1' sprocket orother arrangement may 1.:ersecured to the shaft 59 the latter also actsas a pivot for the channel bar- (58 and its associated parts so that this may-be lifted to permit access to other parts of the machine which arearranged belowit.
